How to grow ore beck on the site?

The mode of reproduction of plants in annual and perennial orebeckia is somewhat different. The fact is that annuals are propagated mainly by seeds, while perennials can be planted by dividing rhizomes. Annual flowers begin to be sown in April or May not in open ground, but in special containers. Seeds do not need to bury too deep into the ground, it is harmful to the plant and will create an obstacle to germination. They are placed on the surface of the soil and slightly sprinkled with it on top. Shoots should be expected after 7-10 days from the time of sowing.

Small plants need to dive, that is, cut the roots of them in order for the plants to become strong and resilient. This procedure is done when the first leaf appears in the rudbeckia. Planting seedlings in the ground is necessary when there is no longer a threat of frost.

Perennial varieties can also be propagated by seed, but in order for the plant to produce flowers in the same year, it is better to plant with rhizomes. Seeds are sown in June or July in a dedicated area of ​​soil, and in early autumn they are transplanted to a permanent place. They will bloom only next year. Rhizomes are divided in spring or autumn. They should be planted in the ground enriched with humus and sand. Before planting, the ground must be kept wet for 2 weeks. In order that the moisture does not evaporate quickly, it is recommended to perform mulching, that is, cover the soil with leaves, dry grass or sawdust.

To collect them from the plant you need to wait until the hearts of the flowers are completely dry, and then cut them and remove the seeds. You can keep them for about 3 years, throughout this period they will maintain good germination. Often, when using seeds collected from their plants last year, I grow flowers with a different color. This is due to pollination between the ore beings of different colors. If the seeds are sown in early spring, in July you can expect the appearance of the first flowers. Most often planted such varieties of annual rudbeckia:

Stems at the end of autumn must be cut, leaving only 10-15 cm. After the rains, the plant will require care. Water should be shaken from the flowers and leaves. Otherwise, tall stems will not be able to resist under the weight of water and bend or break. Before the flowering period, it is necessary to feed the plants, both through the soil, and by spraying nutrient mixtures near the flowers and buds.

These plants must be pruned. Inflorescences that have faded or withered need to be cut off, this will stimulate the emergence of new young buds and prolong the flowering period.

Pests seldom hit rudbeckia. However, leaf nematode attacks can occur which sharpen the leaves of the plant. If the rudbeckia was infected with nematodes, all its fallen leaves must be burned. It is strictly forbidden to add them to the compost, otherwise the pest will appear on other plants. If the nematode loses too many leaves due to nematodes, it will have to be sprayed with special insecticidal preparations.
